Rotatory Motion

A body is said to be in rotatory motion. If it moves about a fixed axis


  • The blades of a fan
  • A spinning top
  • A spinning wheel or a potter's wheel
  • A merry-go-round
  • rotation of the earth about its own axis

A rotatory motion is different from a translatory motion, because in rotatory motion, different parts of the object move through different distances during the same time.The part of the body near the axis of rotation traves a smaller distance than the distant part of the body.
